A multi-player game is simply a game of more than one player per side, typically two versus two. You would divide the forces with your partner, then work together to win the game against the other MP team. You would perform your part of the move, and then send the unadvanced file to your partner. He would move his units, and then advance the file to send to the opposing MP team. The advantage to MP play is that you can discuss strategy with your partner as the game progresses. It provides a good platform for an experienced player to train a new player who is interested in learning. MP games can be used for mentorship.
